EDMUND \VAGEMANN, OF LITTLE ROCK, ARKANSAS, ASSIGNOR OF SIX-SEV- ENTHSTO JOHN D. ADAMS, DEAN ADAMS, OSCAR DAVIS, JOHN W. DAVIS, HORACE G.ALLIS, AND JOHN B. JONES, ALL OF SAME PLACE.

ELECTRIC CAR.

SPECIFICATION forming part of Letters Patent No. 432,501, dated July 15,1890.

Application filed October 1'7, 1889. Serial No. 827,383. (No model.)

To all whom, it flea/y concern.-

Be it known that I, EDMUND \VAGEMANN, a subject of the German Emperor,andaresident of Little Rock, county of Pulaski, and State of Arkansas,have invented certain new and useful Improvements in Electric Cars;(Case 14,) of which the following is a specification.

The invention relates to a type of electricmotor car in which the wheelsof the car form the yoke of the field-magnets.

The object of the invention is to obtain minimum of weight of thecombined truck and motor.

'lhoinvention in all its details is represented in Figures 1, 2, 3, 4,5, (3, 7, 8, and 9. Fig. 1 is a side elevation of the complete device,showing the car-body as well. Fig. 2 is a side elevation of the truckcombined with the motor, the figure being drawn to a larger scale thanthat of Fig.1. Fig. 3 is aplan view of Fig. 2, some portion thereofbeing broken out in order to make room on the sheet. Fig. I- is anelevation of Fig. 2, looking in the direction of the track, which isshown in crosssection. Fig. 5 is a similar view to Fig. 4 ofthe'field-magnet core and yokes. Fig. 6 is a View parallel with theplanes of the wheels of the axle and Wheels mounted thereon, showing howthey may be brought to a common and accurate center before the cores arefastened to them. The figure also shows the axle fixed to the bearings.Part of the axle is broken away, as occupying valuable space otherwise.Fig. 7 is a side elevation of the bearing supporting the axle. Fig. '8is a crosssection of the combined truck and motor, the cylindricalportions of the same being not sectioned. The section is taken in aplane coinciding with the axles axis and perpendicular to the track. Inthis figure the circuits are represented. Fig. 9 shows in a similarsection a modification showing the preferred construction when acylindrical ringarmature is employed.

The device consists of the combination of a car-body a, supported on atruck represented in part by the letter Z), hearings or supports 0, towhich the axles e of the wheels f are fixed in a stationary manner. Thecar-wheels have central holes in the hubs g, through which the axlespass loosely. Upon one hub of each pair of wheels is a commutator h. Thecoils of the armature 2' are electrically connected to the commutator inthe usual. manner, while the brushes bearing on the commutator connectelectrically with both the field-magnets and the generator I.

I11 Fig. 9 the armature is a cylindrical ringarmature o", while in theother figures it is a Siemens or cylindrical armature e. In Fig. 9 thepole-pieces are connected together by non-magnetic material on. In allcases the cores n of the field-magncts are secured, as by bolts 0, tothe wheels, respectively, on opposite sides of the axle.

The axles may be fastened to the bearings c by pins 19.

The wheels in each case form the yoke of the field-magnet, being made ofsuitable iron for thepurpose. Pole-pieces q are provided for the saidmagnets, and are located within inductive proximity to the armature.

Collars 0' are fixed to the axles to prevent the wheels from lateralmotion. t

Then the current is turned on from the electric generator Z, thefieldmagnets and Wheels rotate and propel according to wellknownprinciples of electric induction between the armatures and thepole-pieces.

I claim as my invention- 1. In an electric car, the combination ofstationary axles, rotary wheels mounted th ereon, an armature of anelectric motor fixed upon the axles, and field-magnets of the motorconnecting the wheels and provided with pole,- pieces which are withininductive proximity to the said armature.

2. In an electric car, the combination of field-magnet cores, car-wheelaxles, and carwheels connecting the ends of the cores, the said wheelsbeing of magnetic material and the axes of the cores being parallel tothe carwhcel axles.

8. The combination of two car-wheels, the same being of iron, car-wheelaxles, and fieldmagnet cores joined to the said wheels on opposite sidesof the wheels centers and parallel to the car-wheel axles.

4. In an electric car, the combination of car-axles, hearings orsupports in which the axles are fixed, wheels loose upon said axles,field-magnets connecting said Wheels in pairs,

5 armaturcs mounted upon said axles, commutators on said. Wheels hubsand in circuit with said armatures and field-magnets and with a suitableelectric generator.

5. In an electric car, the combination of IO two car-wheels,field-magnets joiningthesame,

and an armature Wllllill inductive relation to the poles of saidfield-magnets.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two Witnesses, this 22d (lay of August, 15 1889.

EDMUND W AGEMANN.
